Description

TECHNICAL FIELD

[0001] The utility model belongs to tower crane foundation technical field, especially is involved in a kind of isolation tower crane foundation for isolation building construction. BACKGROUND

[0002] Tower crane is also named "tower crane", and it is common hoisting equipment in construction site, which is used for vertical and horizontal transportation of materials and installation of building components. Isolation building refers to the building with isolation layer formed by isolation bearing at the bottom or between floors. Since the horizontal stiffness of isolation bearing is very small, it can effectively block the transmission of seismic energy to the building structure above the isolation layer, and significantly reduce the seismic response of the building structure above the isolation layer. When the height of tower crane is high, the tower body is usually fixedly connected to the building structure by wall attachment device to provide lateral support. The bottom of tower body is fixed to the ground by tower crane foundation. However, when the tower crane is used for isolation building construction, since the building structure attached to the tower crane has an isolation layer, the building structures above and below the isolation layer will have relative horizontal displacement under the conditions of earthquake, wind load or concrete shrinkage, which finally leads to deformation and distortion of the tower body, even to breakage and collapse, causing serious safety accidents. In the prior art, steel pipe scaffold is usually used to connect the upper and lower structures of isolation bearing by column holding or adopt lateral back support during construction stage to limit the relative horizontal displacement of the building structures above and below the isolation layer. Although the above method can prevent the horizontal displacement of building structure to a certain extent, since the mechanical properties and load limit causing displacement cannot be accurately predicted, the design of displacement control measures lacks scientific calculation basis, which leads to insufficient connection reliability, easy loosening and falling, poor overall stability and easy deformation, etc. Therefore, the use of tower crane has uncontrollable safety risks. CONTENT OF UTILITY MODEL

[0003] To solve the above technical problems, the utility model provides an isolation tower crane foundation for isolation building construction, which enables the tower body to move and reset synchronously with the isolation building, effectively improving the safety of tower crane use.

[0004] The utility model adopts the technical scheme of: an isolation tower crane foundation for isolation building construction, comprising a concrete foundation provided with a stepped groove, wherein the stepped groove comprises a lower narrow groove and an upper wide groove; an isolation bearing is arranged in the lower narrow groove; an anti-overturning counterforce beam is arranged in the upper wide groove; a tower crane pedestal is arranged between the isolation bearing and the anti-overturning counterforce beam, a steel ball universal ball is arranged at the top of the tower crane pedestal, and the steel ball universal ball is connected with the tower crane bottom column; and the steel ball universal ball is rollingly connected with the anti-overturning counterforce beam.

[0005] Further, the lower narrow groove is provided with a space matched with the design maximum displacement of the isolation bearing.

[0006] Furthermore, in the initial state, the distance between at least one of the steel ball universal joints and the projected edge of the anti-overturning reaction beam on the tower crane platform is greater than the design maximum displacement.

[0007] Furthermore, the tower crane platform includes an upper connecting plate, a lower connecting plate, and reinforcing ribs disposed between the upper connecting plate and the lower connecting plate; the ball bearing and the bottom column of the tower crane are fixed to the upper connecting plate; the lower connecting plate is fixed to the seismic isolation support by connecting bolts.

[0008] Furthermore, the upper connecting plate is square, the steel ball universal joints are evenly and symmetrically arranged in the middle of the edge of the upper connecting plate, and the bottom column of the tower crane is fixed to the corner of the upper connecting plate.

[0009] Furthermore, the anti-overturning reaction beam has a cross-shaped structure, with the center of the anti-overturning reaction beam aligned with the center of the upper connecting plate. The four supporting beams of the anti-overturning reaction beam extend to the outside of the upper connecting plate in a direction perpendicular to the edge of the upper connecting plate and are fixed to the upper wide groove by embedded parts.

[0010] Furthermore, the ball bearing universal joint includes a fixed rod, a ball seat, and a ball; the fixed rod is threadedly connected to the upper connecting plate; the ball seat is disposed on the top of the fixed rod and has a cavity that matches the ball; the ball is rolled and embedded in the cavity.

[0011] Furthermore, the seismic isolation bearing includes a rubber bearing and an upper flange plate and a lower flange plate disposed at the upper and lower ends of the rubber bearing. The upper flange plate is connected to the lower connecting plate; the lower flange plate is fixed to the lower narrow groove by pre-embedded bolts.

[0012] Furthermore, it also includes a vibration isolation cover plate covering the upper wide groove, wherein the coverage area of ​​the vibration isolation cover plate is larger than the opening area of ​​the upper wide groove.

[0013] Furthermore, the vibration isolation cover plate is provided with through holes that are compatible with the bottom column of the tower crane.

[0014] The advantages and positive effects of this utility model are:

[0015] This application, by setting the tower crane platform on the seismic isolation support, enables the tower body to move horizontally synchronously with the building structure. When a sudden earthquake occurs during construction, or when encountering typhoons, strong winds, or when the seismic isolation building structure moves horizontally due to the drying shrinkage and temperature deformation of concrete, it avoids the torsional deformation or even breakage that may be caused by the fixed connection of the tower crane foundation, and significantly enhances the safety performance of the tower crane under different working conditions.

[0016] By setting up anti-overturning reaction beams and steel ball universal joints, sufficient anti-overturning bending moment can be provided to the tower crane platform without restricting the horizontal displacement of the tower crane platform, thereby avoiding tensile failure of the seismic isolation bearing and further ensuring the safety of tower crane use.

[0017] By scientifically and rationally designing the positional relationship between the steel ball universal joint and the anti-overturning reaction beam, as well as the shape of the anti-overturning reaction beam, it is ensured that even when the tower crane platform undergoes horizontal displacement, the anti-overturning reaction beam can still effectively generate an anti-overturning bending moment on the tower crane platform, thereby improving the stability and safety of the overall structure.

[0018] The anti-overturning reaction beam, tower crane platform, and seismic isolation bearing in this application are all detachably connected, which facilitates installation and disassembly and enables repeated use; the overall structure is stable, the connection is reliable, the construction is convenient, and it has good practicality.

[0029] The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0030] Figure 1 This application illustrates a connection structure between a tower crane and a seismic isolation building in a specific embodiment. The seismic isolation building 9 has several seismic isolation supports 1 at its bottom. The tower crane's body 8 is formed by splicing together standard tower crane sections 81, and is connected to the seismic isolation building 9 via a wall-mounting device 82. In the prior art, the bottom of the tower crane body 8 is directly fixed to a concrete foundation 7 located on one side of the seismic isolation building 9. When the seismic isolation building 9 undergoes horizontal displacement under the influence of earthquakes, wind loads, or concrete shrinkage, a horizontal load is applied to the tower crane body 8 through the wall-mounting device 82. At this time, the upper and lower parts of the tower crane body 8 are simultaneously subjected to opposite forces, making deformation, twisting, or even breakage and collapse unavoidable, leading to a major safety accident. The seismic isolation tower crane foundation proposed in this application allows the tower crane body 8 to move synchronously with the seismic isolation building 9 when it undergoes horizontal displacement, thereby preventing deformation and twisting of the tower crane body 8 and ensuring the safe use of the tower crane.

[0031] like Figure 2 , Figure 3 As shown, this utility model proposes a seismic isolation tower crane foundation for seismic isolation building construction, including a concrete foundation 7 with a stepped groove, the stepped groove including a lower narrow groove and an upper wide groove; a seismic isolation support 1 is provided in the lower narrow groove; an anti-overturning reaction beam 4 is provided in the upper wide groove; a tower crane platform 2 is provided between the seismic isolation support 1 and the anti-overturning reaction beam 4, the top of the tower crane platform 2 is provided with a steel ball universal ball 3 and connected to the bottom column 6 of the tower crane, and the steel ball universal ball 3 is in rolling connection with the anti-overturning reaction beam 4.

[0032] The seismic isolation bearing 1 in this application has good vertical bearing capacity, horizontal elastic restoring force, and damping performance. By installing the tower crane platform 2 on the seismic isolation bearing 1 and then fixing the tower crane bottom column 6 to the tower crane platform 2, the seismic isolation bearing 1 can not only effectively bear the vertical load during the installation and use of the tower crane, but also undergo horizontal displacement when the tower body 8 is subjected to the horizontal tension of the attached building structure. This allows the tower body 8 to undergo horizontal displacement synchronously with the building structure, and to return to its original position synchronously with the building structure after the tension is removed, thus meeting the requirements of tower crane use. To meet the different working conditions required during the construction of the seismic isolation building 9, this application improves the stability and safety of the tower crane. At the same time, since the seismic isolation bearing 1 is not allowed to be subjected to tension during use, this application sets the anti-overturning reaction beam 4 on the upper part of the tower crane platform 2 and connects it to the tower crane platform 2 through the steel ball universal joint 3. This allows the anti-overturning reaction beam 4 to provide sufficient anti-overturning bending moment to the tower crane platform 2 without restricting the horizontal displacement of the tower crane platform 2, thereby avoiding the tensile failure of the seismic isolation bearing 1 and further ensuring the safety of the tower crane.

[0033] In this application, the tower crane bottom column 6 is the column of the standard tower crane section 81 at the bottom of the tower body 8. The lower narrow groove is provided with a space adapted to the design maximum displacement of the seismic isolation bearing 1. Since both the seismic isolation bearing 1 and the tower crane platform 2 are located inside the lower narrow groove, the internal space size of the narrow groove is set according to the design maximum displacement of the seismic isolation bearing 1 so that it can meet the horizontal displacement requirements of the seismic isolation bearing 1 and the tower crane platform 2. Specifically, the cross-sectional shape of the lower narrow groove can be set to a circle, a square or other shapes as needed. Preferably, the cross-sectional shape of the lower narrow groove is designed to be circular, and the distance between the seismic isolation bearing 1 and the tower crane platform 2 and the inner wall of the lower narrow groove is greater than the design maximum displacement of the seismic isolation bearing 1. This design can better adapt to the horizontal displacement requirements of the seismic isolation bearing 1 and the tower crane platform 2 in different directions.

[0034] Furthermore, to ensure that the anti-overturning reaction beam 4 can still effectively exert an anti-overturning bending moment on the tower crane platform 2 when horizontal displacement occurs, in the initial state, the distance between at least one steel ball swivel 3 and the projection edge of the anti-overturning reaction beam 4 on the tower crane platform 2 is greater than the design maximum displacement. This ensures that at least one steel ball swivel 3 always maintains a rolling connection with the anti-overturning reaction beam 4. In other words, even if the tower crane platform 2 experiences maximum displacement, at least one steel column 33 swivel on the moved tower crane platform 2 will still maintain a rolling connection with the anti-overturning reaction beam 4, thereby continuously performing the function of the anti-overturning reaction beam 4 and effectively preventing the tower crane from tipping over. At the same time, when the horizontal tension on the upper tower body 8 of the tower crane platform 2 is eliminated, the steel ball swivel 3 can help the tower crane platform 2 to return to its original position, improving the stability and safety of the overall structure.

[0035] In a specific embodiment, such as Figure 4As shown, the tower crane platform 2 includes an upper connecting plate 22, a lower connecting plate 21, and a reinforcing rib 23 disposed between the upper connecting plate 22 and the lower connecting plate 21; the ball bearing 3 and the tower crane bottom column 6 are fixed to the upper connecting plate 22; the lower connecting plate 21 is fixed to the seismic isolation bearing 1 by connecting bolts; specifically, since the installation surface of the seismic isolation bearing 1 is small, the area of ​​the above-mentioned connecting plate matches the installation surface of the seismic isolation bearing 1, and the area of ​​the upper connecting plate 22 matches the installation area required by the tower crane bottom column 6. By setting up the tower crane platform 2, sufficient installation space is provided for the ball bearing 3 and the tower crane bottom column 6, so that the tower crane and the seismic isolation bearing 1 can be effectively and stably connected.

[0036] Preferably, the upper connecting plate 22 is square, and the steel ball universal joints 3 are evenly and symmetrically arranged in the middle of the edge of the upper connecting plate 22. The tower crane bottom column 6 is fixed to the corner of the upper connecting plate 22. This arrangement can make fuller and more effective use of the area of ​​the upper connecting plate 22, and at the same time make the connection between the upper connecting plate 22 and the anti-overturning reaction beam 4 more stable. Specifically, the tower crane bottom column 6 is arranged at the four corners of the upper connecting plate 22, which can not only evenly transfer the pressure load transmitted by the tower crane to the upper connecting plate 22, but also minimize the area of ​​the upper connecting plate 22. At the same time, several steel ball universal joints 3 are respectively arranged in the middle of the four edges of the upper connecting plate 22. This not only allows them to be staggered with the tower crane bottom column 6, making it easier to cooperate with the anti-overturning reaction beam 4, but also makes the pressure load of the anti-overturning reaction beam 4 evenly transferred to the upper connecting plate 22, thereby making the force on each part of the upper connecting plate 22 more balanced and the overall structure more stable. Furthermore, the connection between the tower crane bottom column 6 and the upper connecting plate 22 is also provided with a reinforcing member.

[0037] Preferably, such as Figure 5 As shown, the anti-overturning reaction beam 4 has a cross-shaped structure. The center of the anti-overturning reaction beam 4 is aligned with the center of the upper connecting plate 22. The four support beams 41 of the anti-overturning reaction beam 4 extend to the outside of the upper connecting plate 22 in a direction perpendicular to the edge of the upper connecting plate 22, and are fixed to the upper wide groove by embedded parts 42. By setting the anti-overturning reaction beam 4 as a cross-shaped structure, it is ensured that the anti-overturning reaction beam 4 has sufficient area to maintain rolling connection with the steel ball universal joint 3, while avoiding the tower crane bottom column 6, so that the tower crane bottom column 6 has sufficient horizontal movement space and can achieve good cooperation with the tower crane platform 2. This ensures the realization of the maximum design displacement of the rubber support 11 and fully utilizes the anti-overturning effect of the anti-overturning reaction beam 4.

[0038] like Figure 6As shown, the aforementioned ball bearing 3 includes a fixing rod 31, a ball seat 32, and a ball. The upper connecting plate 22 is provided with a threaded hole 25, and the fixing rod 31 is provided with a thread that matches the threaded hole 25, and is threadedly connected to the upper connecting plate 22. The ball seat 32 is located on the top of the fixing rod 31 and is provided with a cavity that matches the ball. The ball is rolled and embedded in the cavity. By connecting the fixing rod 31 to the upper connecting plate 22 with a thread, the height of the ball bearing 3 on the upper connecting plate 22 can be easily adjusted to facilitate effective connection with the anti-overturning reaction beam 4, ensuring that the anti-overturning reaction beam 4 can apply an anti-overturning moment through the steel column 33 universal wheel tower crane base 2. Preferably, the cavity can cover more than half of the surface of the ball, so that the ball can roll freely in the cavity without falling out of the cavity. The outer surface of the ball seat 32 is shaped like a hexagonal nut to facilitate the installation and height adjustment of the ball bearing 3 by the operator.

[0039] The aforementioned seismic isolation bearing 1 can be a rubber seismic isolation bearing 1, a steel plate spherical seismic isolation bearing 1, a shape memory seismic isolation bearing 1, or any other seismic isolation bearing 1 capable of achieving seismic isolation, horizontal displacement, and reset effects. Preferably, such as... Figure 7 As shown, the seismic isolation bearing 1 adopts the same seismic isolation bearing 1 as the seismic isolation building 9 to which the tower crane is attached, so that the seismic isolation bearing 1 of the tower crane foundation and the seismic isolation bearing 1 of the seismic isolation building 9 have the same characteristics and design maximum displacement, ensuring that the tower crane can move and reset synchronously with the seismic isolation building 9. In a specific embodiment, the seismic isolation bearing 1 includes a rubber bearing 11 and an upper flange plate 13 and a lower flange plate 12 disposed at the upper and lower ends of the rubber bearing 11. The upper flange plate 13 is connected to the lower connecting plate 21 by fixing bolts 15 passing through the connecting holes 24 on the lower connecting plate 21; the lower flange plate 12 is fixed to the lower narrow groove by pre-embedded bolts 14. In use, the lower flange is always fixed at the bottom of the lower narrow groove. When the tower body 8 is subjected to tension, the rubber bearing 11 deforms, causing the upper flange plate 13 to shift relative to the lower flange plate 12, thereby realizing the synchronous movement and reset of the tower body 8 and the seismic isolation building 9, enhancing the safety of tower crane use.

[0040] Furthermore, such as Figure 8 As shown, the seismic isolation tower crane foundation proposed in this application for seismic isolation building construction also includes a seismic isolation cover plate 5 covering the upper wide groove. The coverage area of ​​the seismic isolation cover plate 5 is larger than the opening area of ​​the upper wide groove, which can effectively seal the stepped groove to prevent personnel from falling in and causing safety accidents, as well as to prevent garbage, rainwater, etc. from falling into the stepped groove and affecting the normal use of the tower crane foundation. Specifically, the seismic isolation cover plate 5 is not fixed to the concrete foundation 7. When the tower body 8 moves horizontally, the seismic isolation cover plate 5 has a sufficient area to maintain the coverage of the stepped groove while moving synchronously with the tower body 8.

[0041] In one specific embodiment, the seismic isolation cover plate 5 is provided with through holes adapted to the tower crane bottom column 6. The tower crane bottom column 6 has sufficient height to pass through the through holes and connect to the tower crane base 2. In another specific embodiment, the seismic isolation cover plate 5 includes a horizontal plate and an inclined plate. The horizontal plate is square, and the inclined plate is trapezoidal and arranged around the horizontal plate. The through holes are located at the four corners where the horizontal plate and the inclined plate intersect. The size of the through holes matches the cross-sectional shape of the tower crane bottom column 6. The bottom of the inclined plate rests on the top surface of the concrete foundation 7 around the upper wide groove. This arrangement ensures that the seismic isolation cover plate 5 has a good sealing effect and can move synchronously with the tower crane bottom column 6.

[0042] This application, by setting the tower crane platform on the seismic isolation support, enables the tower body to move horizontally synchronously with the building structure. When a sudden earthquake occurs during construction, or when encountering typhoons, strong winds, or when the seismic isolation building structure moves horizontally due to the drying shrinkage and temperature deformation of concrete, it avoids the torsional deformation or even breakage that may be caused by the fixed connection of the tower crane foundation, and significantly enhances the safety performance of the tower crane under different working conditions.

[0043] By setting up anti-overturning reaction beams and steel ball universal joints, sufficient anti-overturning bending moment can be provided to the tower crane platform without restricting the horizontal displacement of the tower crane platform, thereby avoiding tensile failure of the seismic isolation bearing and further ensuring the safety of tower crane use.

[0044] By scientifically and rationally designing the positional relationship between the steel ball universal joint and the anti-overturning reaction beam, as well as the shape of the anti-overturning reaction beam, it is ensured that even when the tower crane platform undergoes horizontal displacement, the anti-overturning reaction beam can still effectively generate an anti-overturning bending moment on the tower crane platform, thereby improving the stability and safety of the overall structure.

[0045] The anti-overturning reaction beam, tower crane platform, and seismic isolation bearing in this application are all detachably connected, which facilitates installation and disassembly and enables repeated use; the overall structure is stable, the connection is reliable, the construction is convenient, and it has good practicality.

[0046] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
